computational complexity

[squarefaceyao]

May I ask how to calculate the computational complexity of the minimum and average time I use to solve the problem with PINN?

Just run the code, and record the time?

I'm interested in this discussion as well!
Is there an equation to calculate the complexity of the code like in Eq. 29 in Section A.1 of this paper https://arxiv.org/pdf/2107.07871.pdf ?

How many order of magnitude is the difference in speed between DeepXDE (prediction) over FDM (Execution)?

Looking forward for hearing your thoughts about this.

If you want to use flops for the complexity, then you can simply compute it manually for both DeepXDE and FDM.
